I don't know if you are using options like that:
chromeOptions.AddUserProfilePreference("download.default_directory", @"C:\Temp");
chromeOptions.AddUserProfilePreference("download.prompt_for_download", false);
chromeOptions.AddUserProfilePreference("download.directory_upgrade", true);
chromeOptions.AddUserProfilePreference("disable-popup-blocking", true);
chromeOptions.AddUserProfilePreference("plugins.plugins_disabled", new[] { "Chrome PDF Viewer" });
chromeOptions.AddUserProfilePreference("plugins.always_open_pdf_externally", true);
or
chromeOptions.AddArguments("disable-gpu");
chromeOptions.AddArguments("no-sandbox");
chromeOptions.AddArguments($"--user-data-dir=C:/ChromeProfiles/{_tag}");
I was using those params and now it is removed and working fine.
I don't know if it's only one of those because I removed all...
